I understand, and I see your points. I think if the valve job is good or can be cleaned up cheap, the Speedmasters are the way to go for a very mild street engine that won't see the track or might see it once every blue moon. The Trick Flows are geared towards the more serious street/strip engines. What kills me on both heads are when people don't build a decent combo to compliment the heads, then they automatically blame the heads and say they're crap.
